Effect of TiO2 nanoparticle on wicking phenomenon in PAN nanofiber yarns
In this research, different concentrations of PAN polymeric solutions with various percentages of TiO2 nanoparticles were electrospun to investigate vertical wicking of PAN/TiO2 nanofiber yarns. Results showed by the presence of nanoparticles in the nanofiber structure, the capillary rise increased, although by increasing concentrations of polymeric solutions and nanoparticles, capillary rises were statistically insignificant
Effect of a nano-fibrous structure on the nanofiber mat's hydrophobicity
To improve hydrophobicity, both low surface energy and proper surface roughness are necessary. In this research, the possible surface roughening effect of PET nanofibers was applied to manipulate an appropriate surface topography for the mat composed of them while a fluorocarbon layer generated low surface energy
